Carlos Rogers dominant against Greg Jennings and other observations

-Terrific 4-yard run first quarter/second drive by Kendall Hunter forced the hole inside and then went outside on a play that should have gone for no gain.

-Alex Smith joking and smiling at Clay Matthews while he’s arguing with the officials after a personal foul penalty on Matthews.

-On a play in the first quarter, Delanie Walker had a few steps deep down the field, but Smith went short to Michael Crabtree. If Smith sees Walker, it’s a touchdown.

-Packers wide receiver Randall Cobb is so quick, he had Perrish Cox running circles trying to guard him on a short route. The 49ers expected Cobb to go in motion from the backfield. Cobb had never run routes from the running back position, which was a new challenge for Cobb and the 49ers defense.

-It’s no wonder the Packers can’t run. Justin Smith and Ray McDonald just manhandled the offensive line on run plays.

-In the second quarter, NaVorro Bowman was covering Cobb and Bowman had him stride-for-stride down the field. Impressive.

-This could be a big year for Ray McDonald and Aldon Smith sack wise. At least in this game, those guys had single protection because the Packers constantly doubled Justin Smith.

-At least in this game, there was a big drop off in coverage from Carlos Rogers, Tarell Brown, Chris Culliver and then Perrish Cox. But again, Cox was covering the quickest player in the game out of the backfield.

-Randy Moss went down on his own after an 11-yard gain in the second quarter and I don’t know why. He had running room. Maybe that’s just Moss being Moss.

-Throughout the first half, Alex Smith got rid of the ball rapidly. All but four of his passes were out of his hands under three seconds.

-The offensive line was very good at picking up Packers defensive coordinator Dom Capers’ blitzes in the first half.

-Mario Manningham looked rusty, which is not surprising after missing the back half of the preseason.

-Carlos Rogers is a tough guy, who will stick his nose in there and make good run stops like he did on Cedric Benson early in the third for a 1-yard gain.

-Tight end Delanie Walker blocked really well in this game.

-I still can’t get over how well Rogers played slot receiver Greg Jennings. It was a dominant performance.

NOTE: I’ve only watched the first three quarters. I hope to get to the fourth quarter before everyone stops caring and only wants to hear about the Detroit game.
